Grow a little world. / 种出自己的花园

01 · Seed / 撒种 — Show an open palm, then make a fist to drop exactly one seed in a random place.
张开手掌、再握拳，便会在花园的随机位置落下一粒种子。

02 · Bloom / 生长 — Speak, hum or sing. Loud or sustained sounds help plants grow.
轻声唤醒种子，大一点、持续一点的声音让植物逐渐开花。

03 · Night / 夜晚 — Hold a thumbs-up gesture to switch between day and night. At night, plants stretch taller and glow more brightly.
竖起大拇指切换昼夜；夜间继续发声，花会长得更高、更明亮。

If camera tracking is unavailable, use “Plant 1 seed”; use “Hold to grow” as a voice fallback and the ☾ button to change day/night. 建议通过 VS Code Live Server 打开网页。
